Rot Box’s Superduty

[Rot Box]

Thanks Mouse you’ve been a great help to me I appreciate it.

I tested the system today with my home brew tester and found a massive leak on the driver side plenum where it meets the head. oh man not the news I wanted to hear I’m surprised it boosts at all that’s how bad it is. I’m looking into billet plenums with o-rings instead of grey rtv the stock ones use. Not sure if they’ll fit though as I have an off year E99...

Here’s some pics. If anyone wants to borrow my tester you’re more than welcome to it. Really takes the guess work out of it. Just insert past the crank vent in the intake tube and pump it up to 20psi. Easy peasy. For the 7.3 use a 3” pipe cap.

Good that you know whats happening. Once it's fixed the engine will be a whole new animal

Ordered stainless bellowed up pipes, the plenum inserts (to prevent crushing where the clamps attach), ebpv delete pedestal, ebpv delete exhaust housing, cac boots etc etc..

I’ll post some pics and take you guys along for the ride! Gonna start on it Wednesday.

Good parts on order. The EBPV delete saved my truck some EGTs and the up pipes did a good job sealing leaks (they are a pain to install though).

I have not used a leak tester on my truck, I might have to borrow yours sometime.

Diving in! So far it’s been straight forward. Just fighting the clamp on the back of the turbo where it meets the collector.. oye!

 

[Rot Box]

Making progress! Turbo is it out!

Inserts are installed. These keep the plenums from crushing under too much clamp pressure.. nice little upgrade.

Minus one stripped hose clamp it’s all back together! Hope the boost is back.. overall it wasn’t too hard of a job just time consuming. The clamp on the back of the turbo was a pain in the ass getting off and on but I got it.

Nice work! Hope it boosts now.

 

[Rot Box]

Wow what a difference that made. She runs so good now! You can feel it de-fuel at around 23psi which is normal and the egts stay nice and low. Very happy with the results 😎

I’ve put about 300 miles on it so far and man it’s a whole new truck boost comes on strong and egts have stayed well within the safe zone. Took my mileage too (off the odometer) and after mostly freeway driving at around 70mph it’s getting 19.3mpg. Couldn’t be happier with it. Should have plenty of power to pull my camp trailer now! 😎

 

[Rot Box]

Pulled my trailer to the lake for the weekend with family and friends! Having the boost back was very noticeable and the egts stayed nice and low. The real test will be Logan canyon in two weeks it’s a steep one—headed to Wyoming’s badlands with the bikes 😎

I bet you literally barely knew that was back there

Man that's a good looking truck/trailer combo!

 

[Rot Box]

Oh man... leaving a 3” puddle of oil every time I park it. It just popped up a few days ago. Thinking I must of punched an oring or something during reassembly but I don’t know. Everything went back together so nicely but there is a puddle under the pedestal so I can only assume that’s where it’s coming from. Always something isn’t it? 😓

 

[DAA]

Yup always something...

I've replaced the OEM lines with aftermarket units that only have 1 o-ring per side (OEM has 3). I've also had the "unservicable" plug on the HPOP leak, but the repair kit from Diesel o-rings fixed it.

 

[Rot Box]

If anyone needs help pulling their 7.3 turbo I’m your man hahaha. Got it out in 45 minutes flat!

Pedestal to block and turbo to pedestal is dry as a bone so I’m pretty sure that’s not where the leak is. Had to pull everything off to see that. One plug in the passenger side oil rail is damp I’ll be able to watch that one with it running otherwise everything looks dry and problem free. We’ll see... I’m putting it back together now.

Can’t find this dang leak to save my life!

Haha, you sound a lot more confident now vs this morning when we talked. I told you these motors are simple.
